Story summary: When Xi Chen opened his eyes, he found that he was in a prehistoric world where heaven and earth had not yet opened, and dragons and phoenixes had not yet been robbed. He is not a human being, nor is he an innate god or demon. He is just a newly hatched... Little crow? In this terrifying era when Da Luo is everywhere and golden immortals are no better than dogs, Xi Chen's only reliance is his strange magical power that can devour all things and analyze their original laws. In order to survive, and not to be regarded as some powerful snack, he could only devour and become stronger along the way, from an inconspicuous little demon to the peak of eternity step by step, becoming the one who is superior to the saints in the sky... The first demon in eternity.
